NOTE: AFR (Mearsured) = Dyno AFR sensors. AFR (Actual-B1), AFR (Actual-B2) are the BMW O2 sensors. There seems to be a difference between the two; a difference that is not normally seen during dyno tests. One or the other is out of calibration, and by the looks of it, the dyno AFR sniffer looks like it's out of calibration, as we can see in RunFile_023 the dyno AFR is completely wrong, but in RunFile_022 the dyno AFR matches BMW O2 sensors perfectly. Moral to the story: BMW O2 sensors are correct, but dyno RunFile_023 isn't.

Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
